hey man i saw your chats and i say differently on chopping its tail while the rathalos charges ive done it several times all you have to do is dodge out of the way as hes coming and thats your que make sure your really close as soon as you dodge him then attack his tail while hes trying to get up then run like on fire. it works all the time but it takes a gamer to actually go up to this challenge

i have a tip for you MHserious on hitting the tail without getting buffeted by the the wind from the rathalos just as soon as he lands give yourself a second before you rush in because if you rush in to early your more than likely to mess up but if you can figure out getting pass this it should be no problem
